Streetporting remains one of the most popular rotary engine modifications because it offers substantial airflow improvements without sacrificing overall drivability.

This streetported 13B motor benefits from:

• Improved volumetric efficiency
• Enhanced throttle response
• Increased horsepower potential
• Better breathing at higher RPM
• Strong mid-range performance

Compared to stock porting, the streetport configuration unlocks additional power while maintaining a practical driving experience suitable for both street and track environments.
